Lysek said that Poplawski, of Totem Trail, had been scuba diving at Dutch Springs, a private facility just north of Bethlehem, Pa., at around 8:30 p.m. Saturday. He was reported missing at about 11:30 p.m.

Emergency personnel were called to the scene and Poplawski's body was recovered about 3:15 a.m.

Information on the facility's website said that "to dive at Dutch Springs you must have a buddy or a current solo diving certification card." The facility does not hold certification classes for scuba diving, the website says.

Poplawski, who Lysek said was "an experienced diver," was pronounced dead at the scene.

Lysek said Poplawski's death was not the first drowning at the facility, but the coroner said he did not know how many there have been since Dutch Springs opened in 1980.

"I don't keep statistics," Lysek said Monday afternoon.

Stuart Schooley, Dutch Springs' owner, declined to answer questions about Poplawski's death because, he said, the incident is still under investigation by the coroner's office. Schooley also declined to say how many deaths there have been at the diving site.

Schooley said Dutch Springs is a 50-acre lake. Scuba divers there can "explore underwater platforms, submerged vehicles, aircraft and other unusual sites," according to the business' website.
